Abstract
A trim panel, which is composed of a substrate of corrugated paperboard and a decorative and/or protective skin layer, is produced by press-forming the substrate into a desired shape by a hot-press, parting the movable die of the press from the stationary die to leave the shaped substrate in the latter die, dragging a sheet material employed as the skin into the press so as to stretch above the shaped substrate, and pressing the stretched skin material against the shaped substrate, interposing an adhesive layer therebetween unless the skin material has an adhesive property, with application of heat to accomplish adhesion. The hot-press is combined with a substrate feed mechanism and a skin material feed mechanism which includes a piston rod with a sheet-grasping device mounted thereon and can serve also the function of withdrawing the shaped and laminated product from the stationary die. At the second pressing, adjustment of the clearance between the dies according to the thickness of the skin is effective for achieving a uniform adhesion of the skin to the substrate without deforming the substrate.
